The DeGraaf & DeGraff (additional spellings) Genealogy DNA Project was initiated to help identify and group our family lineages. We are looking for additional participants. Individuals interested in collaborating on family history and using genetic testing to assist our research efforts are encouraged to join.

If you are a male with one of the included surnames and are interested in researching your direct paternal line further, you can participate. This project study is using the DNA test that looks at a portion of the DNA called the Y chromosome. The Y chromosome is unique to males and can be used to identify one's direct paternal line. For this reason, females cannot contribute directly, but can find a male relative (father, brother, cousin, etc) to be tested as a representative of her line. Additionally, anyone related to a person with a surname who is included in our surnames of interest and willing to share their paper trail ancestry findings are invited to join.
